    <p class="a">明月几时有,把酒问青天。</p>
    <p class="a">不知天上宫阙，今夕是何年?</p>
    <p class="a">我欲乘风归去，又恐琼楼玉宇，</p>
    <p class="a">高处不胜寒。</p>
    <p class="a">起舞弄清影，何似在人间？</p>
    <br/>
    <p class="b">转朱阁，低绮户，照无眠。</p>
    <p class="b">不应有恨，何事长向别时圆？</p>
    <p class="b">人有悲欢离b，月有阴晴圆缺,</p>
    <p class="b">此事古难全。</p>
    <p class="b">但愿人长久，千里共婵娟。</p>
